ex 2
1)
tradition = x
reverie = 3+x
passion = 2(3+x) = 6+2x
folie = 6+2x +8 = 2x +14
2) 8 bouquets de chaques
8x + 8(3+x) + 8(2x+6) + 8(2x+14)
= 8x + 24+8x + 16x + 48 + 16x + 112
= 48x + 184
3) tradition = x = 7
7*2,2 = 15,4 euros
reverie = 3+x = 3+7 = 10
10*2,2 = 22 euros
passion = 2x+6 = 2*7 +6 = 14+6 = 20
20*2,2 = 44 euros
folie = 2x + 14 = 2*7 +14 = 14+14 = 28
28*2,2 = 61,6 euros
4) reverie = 22 euros
folie = 61,6 euros
22+61,6 = 83,6 euros ( prix sans reduction )
83,6(1-15/100) = 71,06 euos ( apres reeduction )
voila j espere t avoir aider
